SPINNING RING.- APPLICATION FILED lUNEB. 192a.

Patented July 18, 19221 SPINNING RING.

Application filed June 8,

To all 7.0710722 it may concern:

Be it known that I, CHARLES A. HOLT, a citizen of the United States, and resident f'Cainbridge, county of Middlesex, State of Massachusetts, have invented an Improvement in bpinning Rings, of which the following description, in connection with the accompanying drawing, is a. specification, like characters on the drawing representing like parts.

This invention relates to spinning rings of the type exemplified by United States Patents No. 957,759, May 10, 1910 and No. 1,833,-

072, March 9, 1920 and one object of the in vention is to provide an improved spinning ring of this type which is constructed so as to reduce the friction on the traveller when the ring is started up thereby enabling fine yarns to be spun without danger of breaking when the spinning frame is set in operation.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

Fig. I is a plan view of a spinning ring embodying my invention.

Fig. 2 is a plan view of the under member of the casing.

Fig. 3 is an en 3 3, Fig. 1.

Fig. 4- is an enlarged section on the line t-4, Fig. 2.

Fig. 5 is a fragmentary view showing modification.

The spinning ring comprises a metal casing formed of the under member 1 and upper member 2 vhich are detachably secured together and a lining member 3 of self-lubricating material, such for instance, as wood treated in oil, which is enclosed between the upper and under members 1 and of the casing and is provided with the annular traveller-receiving recesses i in which the annular traveller 5 operates, said travellerhaving the upstanding stem 6 terminat- .ing in the guide eye 7.

The above described parts are such as are usually found in spinning rings of this type.

In this spinning ring the undermember 1 is provided with the annular flange 8 on which the liner rests and the inner edge of said flange is bent upwardly as shown at 9 larged section on the line Specification of Letters Patent.

speed it will be is rotating at practically In order to reduce the friction to which the traveller is subjected when it is being i started up I propose to make the support 9 in the form of tlons which are separated supporting porspaced from each other the spaces 10 and I propose further to upset the ends of each supporting portion 9 as shown at 11 thereby to form separated points of support for the traveller. These are provided upset portions 11 12 on which t v 1 I 1'' p01 tlng sui races with flat su he ring rests,
